This is the "T900Ultra2," a smart watch with a large 2-inch screen. It's a foreign product, but I think it's well-made. I don't know the detailed usage, but it seems to have various convenient functions for people who play sports. Please use it after charging. It will be shipped via Yu-Packet Post (mini) for anonymous delivery. I am not familiar with this type of product and cannot provide support or handle issues, so I am offering it at a lower price. Also, since it is an imported product, there may be some damage to the outer box. Please purchase only if you understand this.
